Total eigenvalues

    Hi.
    How do you calculate Total eigenvalues smaller than a certain value in Matlab?

    Perhaps you could give a little more detail.
    What is your application?
    Are you working with real or complex eigenvalues?
    By total, do you mean total number of eigenvalues...as in you are looking for a count?
    If that is the case, I would do something like:
    E = eig(A);
    F = find(abs(E) < c);
    size(F)
    Where A is your matrix, and c is your "certain value".
